Views don't have stored execution plans, because they're just saved SQL statements and are replaced by their definition early in the parsing phase of a query. They're not executed in their entirety like procedures or functions are.

When you query a view, from inside a procedure or ad-hoc query, the resulting query is optimised and its plan stored depending on the normal rules of caching and reuse.

p.s. All queries use an optimised execution plan, I think you mean 'cached execution plan'

Auto update statistics has no effect whatsoever on how plans are cached in a database.
